FIG. 1 is a perspective view of an end cap for a paper tube showing my new design.

FIG. 2 is a top view of the end cap of FIG. 1.

FIG. 3 is a front side view of the end cap of FIG. 1, with the right, back and left side views being identical to the front side view; and,

The matter shown in broken lines in the figures is present solely to indicate an exemplary perimeter rim of the end cap, and does not form part of the design.
